The First World War represents the end of a dream of a peaceful world. For the first time the most important state face off in a new kind of war, a modern war, that will involve not only the soldiers, but also the civilian population.

The consequences of this war will have strong repercussions throughout Europe and the peace treaties that give birth to a fragile balance of power, a fragile construction that will fall tragically in the next two decades.
